BACKGROUND: Chinese medicine Gukang prescription has a clear effect on clinical treatment of osteoporosis, but the therapeutic pathway is stil unclear.
OBJECTIVE:To investigate the effects of Chinese medicine Gukang on the expression of receptor activator of nuclear factor kappa B ligand and osteoprotegerin by regulating core binding factor alpha 1 expression to control the growth and development of osteoblasts.
METHODS:Sprague-Dawley neonatal rats within 24 hours after delivery were used for the separation and culture of osteoblasts. Adult Sprague-Dawley rats were used to prepare drug-containing serum, and then divided into two groups randomly:normal control group and Gukang group. Rats in the normal control and Gukang groups were intragastrical y administrated with extract of Gukang prescription and normal saline based on rat’s body surface area, for 1 consecutive week. Two hours after the last administration, blood samples were taken from the heart. Then the serum was col ected. Osteoblasts at passage 3 were confirmed with alkaline phosphatase assay and digested. After counting and planting, al osteoblasts were divided into two groups and treated with col ected
serum for 72 hours. Proliferative rate of osteoblasts was detected by using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide test. Secretion of alkaline phosphatase was detected by using enzyme linked immunosorbent assay and corrected with the corresponding absorbance value. mRNA expression of core binding factor alpha 1, receptor activator of nuclear factor kappa B ligand and osteoprotegerin were detected by using reverse
transcription-PCR in al groups.
RESULTS AND CONCLUSION:mRNA expression of osteoprotegerin and core binding factor alpha 1 in the Gukang group was significantly higher than that in the normal control group, but protein and mRNA expression of receptor
activator of nuclear factor kappa B ligand were dramatical y lower in the Gukang group compared with the normal control group (P<0.01). These findings indicate that Chinese medicine Gukang prescription can modulate the expression of
core binding factor alpha 1, thereby adjusting the expression of receptor activator of nuclear factor kappa B ligand and osteoprotegerin, which may be one of the mechanisms underlying Gukang treatment for osteoporosis.

Objective:To explore the mediating role of insomnia between childhood trauma and suicide risk in middle school students.Methods:Childhood trauma questionnaire(CTQ), insomnia severity index(ISI) and suicidal behaviors questionnaire-revised(SBQ-R) were used to investigate 3 442 middle school students.According to the total score of the SBQ-R, those who scored less than or equal to 6 were divided into low suicide risk group, and those who scored more than or equal to 7 were divided into high suicide risk group.In this study, there were 2 168 students in the low suicide risk group and 1 274 students in the high suicide risk group.SPSSAU 21.0 online statistical software was used for common method deviation test, descriptive statistics, variance analysis and correlation analysis, and structural equation model was constructed, and Bootstrap method was used for mediation effect test.Results:(1) There were statistically significant differences between the high suicide risk group and the low suicide risk group in terms of grade and gender( χ2=11.144, 83.737, both P<0.05), and there were statistically significant differences in the types of childhood trauma and the severity of insomnia( χ2=292.211, 333.998, both P<0.05). (2) The total score of childhood trauma in the high suicide risk group (43.92±10.50) was higher than that in the low suicide risk group (37.74±6.93) ( F=351.78, P<0.01), and the score of insomnia in the high suicide risk group (10.66±5.54) was higher than that in the low suicide risk group (7.04±4.76) ( F=379.25, P<0.01). (3)The total score of childhood trauma was positively correlated with the score of suicide risk ( r=0.415, P<0.01), and the total score of childhood trauma was positively correlated with the score of insomnia ( r=0.306, P<0.01), and the score of insomnia was significantly positively correlated with the score of suicide risk ( r=0.399, P<0.01). After controlling for demographic data, anxiety and depression, the correlation was still significant ( P<0.01). (4) Path analysis and mediation test showed that childhood trauma had a positive effect on insomnia ( β=0.30, P<0.01), insomnia had a positive effect on suicide risk ( β=0.29, P<0.01), and childhood trauma had a positive effect on suicide risk ( β=0.33, P<0.01). The mediating effect of insomnia accounted for 21.21% of the total effect.After controlling for demographic data, anxiety and depression, the mediating effect accounted for 10.66% of the total effect. Conclusion:Childhood trauma and insomnia have a significant impact on the suicide risk among middle school students.Insomnia plays a partial mediating role between childhood trauma and middle school students' suicide risk.Timely management of the sleep disturbances of traumatized individuals can reduce the suicide risk among middle school students.

ObjectiveTo clarify the relationship between childhood maltreatment and insomnia in middle school students, and to explore the mediating role of post-traumatic stress disorder (PTSD) symptoms and the moderating role of mental resilience involvement. MethodsFrom April to May 2021, a total of 3 412 students in 3 middle schools in a city in western China were selected using convenient sampling method, and all students were assessed by Childhood Trauma Questionnaire (CTQ), Post Traumatic Stress Disorder Scale (PCL), Insomnia Severity Index (ISI) and mental resilience scale. The moderated mediating effect analysis was conducted using Process v3.4. ResultsAmong the middle school students, CTQ scores were positively correlated with PCL and ISI scores (r=0.540, 0.320, P<0.05), and the scores of CTQ, PCL and ISI were negatively correlated with the score of mental resilience scale (r=-0.049, -0.193, -0.132, P<0.05). PTSD symptoms exhibited a partial mediating effect on the relationship between general childhood maltreatment and insomnia (β=0.161, P<0.05), accounting for 80.5% of the total effect. ConclusionAmong the middle school students, the relationship between childhood maltreatment and insomnia is partially mediated via PTSD symptoms, and mental resilience exerts a moderating role between childhood maltreatment and PTSD symptoms.

ObjectiveTo investigate the mediating role of loneliness and social anxiety in the relationship between basic psychological needs satisfaction and smartphone addiction among high school students, and to provide references for the intervention to smartphone addiction for high school students. MethodsIn April 2022, a total of 14 666 high school students from 5 middle schools in a county of Sichuan Province were included by random sampling method. Basic Psychological Needs Scales (BPNS), the UCLA Loneliness Scale-3 edition (UCLA-3), Interaction Anxiousness Scale (IAS) and the Mobile Phone Addiction Index (MPAI) were used for cross-sectional investigation. Bootstrap method was used to analyze the mediating role of loneliness and social anxiety in the relationship between the basic psychological needs satisfaction and smartphone addiction. Results① In this study, 14 036 valid questionnaires were returned, and 1 752 (12.48%, 95% CI: 0.114~0.136) high school students were found to be addicted to smartphone phone. The BPNS score was negatively correlated with UCLA-3, IAS and MPAI scores (r=-0.771, -0.486, -0.417, P<0.01). And MPAI score was positively correlated with IAS and UCLA-3 scores (r=0.403, 0.424, P<0.01). IAS score was positively correlated with UCLA-3 score (r=0.458, P<0.01). ②The degree of basic psychological needs satisfaction in high school students can directly negatively predict smartphone addiction (β=-0.383, P<0.05), and can also indirectly affect smartphone addiction through loneliness and social anxiety (β=-0.130, P<0.05). ③Loneliness (indirect effect value was -0.145) and social anxiety (indirect effect value was -0.074) partially mediate between the basic psychological needs satisfaction and smartphone addiction. Loneliness-social anxiety also has significant chain mediating effect (indirect effect value was -0.034), which accounted for 8.88%. ConclusionThe basic psychological needs satisfaction can not only directly affect the occurrence of smartphone addiction, but also indirectly affect the occurrence of smartphone addiction through the chain mediation of loneliness and social anxiety.
